Heavy-ion collisions at high energies calls for new technical solutions to cope with the very high multiplicities of produced particles. In this thesis the design and development of two types of tracking chambers for high multiplicity environments are presented. The first type was developed to be a part of the tracking system of the WA98 experiment. The tracking chambers were designed to provide

A chemotaxonomic method for classification of asymmetric penicillia by means of cross-partition in aqueous two-phase systems combined with SIMCA pattern recognition analysis. Conidia of three strains each of three closely related Penicillium species in the P. oiridicatum group were subjected to cross-partition in aqueous polymer two-phase systems. The cross-point values, the percentage of conidia

Objective. To investigate the adjusted relative risk of cardiovascular disease (CVD) events in offspring of parents with cardiovascular mortality before 75 years. Setting. The city of Malmö, Sweden. Design. A follow-up study based on register linkage analyses. Subjects and methods. In the Malmö Preventive Project (MPP), a total of 22 444 men and 10 902 women attended the screening programme bet

Popular Abstract in Swedish Forskning och studier av ytvattensystem i sudanesiska röda havsområdet för utveckling av relevant metodik medför ett antal konceptuella svårigheter. Ett huvudsakligt problem är den begränsade tillgången till litteratur och mätdata för modellutveckling. En annan svårighet är tillämpligheten av redan existerande metoder och modeller utvecklade i andra regioner. För att bThe magnitude and availability of surface waters in the arid/semi-arid Sudanese Red Sea region has been examined. In conjunction with the research objective, opinions and methodologies applied by previous researchers have been assessed. The study applied a geographical hydrological synthesis within a GIS framework. As a system with advanced geo-modelling capabilities, GIS is used to integrate spat

Pt (0.1 wt.%) on Al2O3, TiO2, and MgO supports were used for the low temperature combustion of methanol in both the absence and the presence of ammonia. Without NH3 in the gas the performance for the complete combustion decreases in the order Pt/MgO greater than or equal to Pt/TiO2 much greater than Pt/Al2O3 comparing a fixed amount of Pt surface area. In the presence of ammonia strong deactivatio

OBJECTIVE: To compare costs of transurethral prostatic resection (TURP) and transurethral microwave thermotherapy (TUMT) for symptomatic benign prostatic hyperplasia (BPH) in a randomized, controlled trial. METHODS: In 70 BPH patients all costs were calculated for management, including complications and repeat treatment, during TURP or TUMT and 24-month follow-up. Clinical outcome was judged from

Some patients with hearing impairment cannot use conventional hearing aids. One solution for these patients is the use of bone conduction hearing aids; however, this kind of equipment is associated with several problems related to the necessity for a good contact between the transducer and the temporal bone. Direct bone contact would be an ideal solution provided that safe and reaction-free skin p

In this study, a method was developed for determination of the free concentration of 4-isobutylacetophenone, a toxic degradation product of ibuprofen, in river and sewage water samples from Sweden. Sample preparation and analysis were performed by a hollow-fibre microporous membrane liquid-liquid extraction (HF-MMLLE) set-up and gas chromatography-mass spectrometry (GC-MS), respectively. In this n

The prediction of transcription factor binding sites in genomic sequences is in principle very useful to identify upstream regulatory factors. However, when applying this concept to genomes of multicellular organisms such as mammals, one has to deal with a large number of false positive predictions since many transcription factor genes are only expressed in specific tissues or cell types. We devel

The usefulness of dietary strategies against cardiometabolic risk is increasingly being acknowledged. Legumes and whole grains can modulate risk markers associated with cardiometabolic diseases, but their possible additive/synergistic actions are unknown. The objective of the present study was to assess, in healthy subjects, the effect of a diet including specific whole-grain barley products and l

The function of articular cartilage depends on its structure and composition, sensitively impaired in disease (e. g. osteoarthritis, OA). Responses of chondrocytes to tissue loading are modulated by the structure. Altered cell responses as an effect of OA may regulate cartilage mechanotransduction and cell biosynthesis. To be able to evaluate cell responses and factors affecting the onset and prog

The implementation of new surgical techniques offers chances but carries risks. Usually, several years pass before a critical appraisal and a balanced opinion of a new treatment method are available and rely on the evidence from the literature and expert's opinion. The frozen elephant trunk (FET) technique has been increasingly used to treat complex pathologies of the aortic arch and the descendin

In this study, the potential of a chitosan-agarose-gelatin (CAG) cryogel scaffold for the repair of subchondral cartilage defects was explored in female New Zealand white rabbits. Custom-made CAG cryogel scaffold was implanted in a surgically created subchondral defect (diameter of 4 mm, depth of 4 mm) in knee joint of rabbit. The repair of the subchondral defect was evaluated at regular time inte

Purpose of the Study: To identify risk factors for early nursing home placement (NHP) in Alzheimer's disease (AD), focusing on the impact of longitudinal change in cognition, activities of daily living (ADL), service utilization, and cholinesterase inhibitor treatment (ChEI). DESIGN AND METHODS: In an open, 3-year, prospective, multicenter study in a routine clinical setting, 880 AD patients were
